While the greatest savings using fieldbus technology are realized in new installations, it can also be a major advantage in modernizing brownfield facilities, as illustrated by a nuclear power plant example:

•Move from pneumatic and analog systems to fully digital instrumentation and control in one step•Save cost and effort by avoiding intermediate and stepwise approaches•Creating future-proof field networks and I/O compatible with legacy and modern control platforms•Lay groundwork for more sophisticated control and asset management systems
